Allred said she has the proof that what Rodgers claims is true.
"In response to Faith's lawsuit, Mr. Kelly retaliated against her by threatening to reveal what he alleges are details of her sex life," she said. "In addition, he has posted private photos of her."
Kelly, who has faced decades-long claims of sexual misconduct with underage girls, is under new scrutiny following the release of the Lifetime documentary "Surviving R. Kelly."
